iOS 7 Might Keep You From Playing Diablo 3 Or World Of Warcraft

Downloading iOS 7 might improve your experience with your Apple device but it could have some drawbacks for your gaming. Blizzard warns that upgrading your device's operating system might screw up the Battle.net Authenticator attached to it.

The Authenticator is a free app that helps secure your Battle.net account for World of Warcraft, StarCraft 2 and Diablo 3. The app generates a one-time numeric code that you must use along with your account password in order to sign in. It's a handy tool to prevent hackers from accessing your account information or mucking up all your game progress. It will also prevent that Hearthstone beta access you just received.

However, Blizzard says that the iOS 7 update could reset your authenticator. This would prevent you from being able to access your account. The company recommends that you take one of the following steps in order to prevent any disruption to your gaming:

Sign up for the free SMS Protect service. In the event of a lost, broken, or accidentally reset authenticator, users with SMS Protect can remove the old authenticator from their account with a texted security code. For more information, visit the SMS Protect FAQ.

Write down your authenticator's Serial Number and Restore Code so that you may restore your authenticator to your phone after the OS update is finished.

Temporarily remove the authenticator before updating. Reattach the authenticator again once your iOS update is complete.

Update over Wi-Fi. iPhones that are updated over Wi-Fi rather than through a computer are less prone to accidental resets.

Blizzard also offers a keychain authenticator in a variety of styles. However, it's $6.50 and could end up breaking on you. In spite of the iOS 7 hiccups, the mobile version of the authenticator is your best bet.

iOS 7 was officially released yesterday. The update contains a number of UI changes, ranging from borderless buttons to dynamic font size. Apps now have full multitasking and automatic downloading. The A.I. assistant Siri offers new voices and can perform a wider range of tasks. Even if you don't care about most of that: woo, new buttons!
